Abstract The complexes [M(CO)_3(CH_3CN)_3](M=Mo, W)react with an equimolar quantity ofPhSnCl_3 in dichloromethane at room tempreture to afford new heterobinuclearcomplexes [PhCl_2SnM(Cl)(CO)_3(CH_3CN)_2] [M=Mo(1); W(2)]. The complexes reactwith two equivalents of PR_2R’(R=Ph, R’=Ph, Me; R=Cy, R’=H) to yield stablecomplexes [PhCl_2SnM(Cl)(CO)_3(PR_2R’)_2]. Reaction of[PhCl_2SnM(Cl)(CO)_3(CH_3CN)_2]with one equivalent of PPh_2(CH_2)nPPh_2(n=I,2) or bulky phosphine ligands PBu_2~tClin dichloromethane at room tempreture to give [PhCl_2SnMo(Cl)(CO)_3{PPh_2(CH_2)n-PPh_2}] .CH_2Cl_2, [PhCl_2SnMo(Cl)(CO)_3PBu_2~tCl]. CH_2Cl_2, respectively. The complexes1 and 2 react with phosphite donor ligands P(OMe)_3 to give [PhCl_2SnM(Cl)(CO)_2-{P(OMe)_3}_3]. All complexes have been characterized by elemental analysis, IRand ~1HNMR spectroscopies. Here we report the preliminary results of this work.
Abstract The complexes [M (CO) _3 (CH_3CN) _3] (M = Mo, W) react with an equimolar quantity of PhSnCl_3 in dichloromethane at room tempreture to afford new heterobinuclear complexes [PhCl_2SnM (Cl) (CO) _3 (CH_3CN) _2] [M = Mo (1); W (2)]. The complexes react with two equivalents of PR_2R ’(R = Ph, R’ = Ph, Me; R = Cy, R ’= H) to yield stable complexes [PhCl_2SnM (Cl (CH_3CN) _2] with one equivalent of PPh_2 (CH_2) nPPh_2 (n = I, 2) or bulky phosphine ligands PBu_2 ~ (PR_2R) _2] tClin dichloromethane at room tempreture to give [PhCl_2SnMo (Cl) (CO) _3 {PPh_2 (CH_2) n-PPh_2}] .CH_2Cl_2, [PhCl_2SnMo (Cl) (CO) _3PBu_2 ~ tCl]. CH_2Cl_2, respectively. The complexes1 and 2 react with phosphite donor ligands P (OMe) _3 to give [PhCl_2SnM (Cl) (CO) _2- {P (OMe) _3} _3]. All complexes have been characterized by elemental analysis, IRand ~ 1H NMR spectroscopies. Here we report the preliminary results of this work.
